To allwhom it may, concern:

Be it known that I, HENNING; HALL:

STREAM, a citizen of the United States, resid-v exact description of theinvention, such as;

will enable others skilled in the artto which; it appertains to make anduse the same,

The invention relates paper feeding machines in which a bank of Vfeathered or fanned out sheets is fed to combing wheels or othersheetseparating de-. vices; which separate the sheets and advance the topsheet so that it may be removed or presented to machines forfurthermanipu-V lating or acting upon it.

In paper feeding machines ofthe continu one type the bank of sheets issupplied to the feed table of; the machine by a loader comprisinganupper supply table on to which the sheets are loaded: by the attend.ant, and a curved throat which inverts the bank and reverses itsdirection, of move.- ment; as it passes from the supply table to thefeed table. Under certain conditions it:

maybe desirable to maintain the supply'of' sheets by building on to therear end of'the bank on the feed table, instead of utilizing the loader,as, for instance, in teeding sheets which by reason of their small size,or for other; reasons, may not pass properly through the feed throat,and it is the: object of the present invention toiprovide a constructionwhich will enable thisv to.be reads ilyand conveniently done.

To this end the invent on contemplates: so 4 mounting the loader, and soconstructingand arranging: the bank-feeding mechanism,

that the loader may be moved intov or out of feeding operative relationwith the bankand sheet; separating mechanisms, This enables the loaderto be positioned to cooperate with the bank feeding and sheet separatingmechanisms in the usual manner or to bemovedback into, position to giveready. access' to the bank on the! feed table, and to enable theattendant to readily build on to the rear end ofthe bank of sheetsthereon The invention will be readily understood from an inspection ofthe accompanying V drawings 3,1'ldthe following detailedwde to thatclass V of s rip i ni o he ech n sm l strate thereth draw ngs, Fig re lis a. i -e eratlon; showing so much of continuous paper ing mach ne. asi e ssary s. l tr te. he. applica icn f the pr sent; mprov me ts:thereto, and Fig. 2 is detail sectional view n neZQ Fig? l.-. 1 V

mechanism, by gearing 17 connecting the drum and pressure rolls with agear 18 on the shaft 9.

In embodying the present invention in a machine having the constructionthus far position to give access to the rear part of the feed tapes 8,and to the parts which'are normally rendered either inaccessible or 1n-'convenient of access by the parts of the loader. The gearing 17 is alsopreferably so arranged that it may be brought into and out of mesh withthe gear 18 by movement of the loader. Themechanism for actuating thefeed tapes 8 is also preferably so constructed and arranged'that it willnot be affected by movement of the loader into and out of operativeposition. In the construction shown, the side frames 19 of the loaderare provided with flanges 21 arranged to embrace the guide bars 20, andthe upper edges of the bars are provided with rack teeth 22 which areengaged by pine ions 23 formed on the ends of a shaft 24 mounted in theside frames. The ends of the shaft 24 may be provided with projectionsor sockets .25 to receive a wrench or crank handle, so that the shaftmay be conveniently turned to slide the loader back:

and forth on the guide bars.

The mechanism for actuating the tapes 8 of thebank'feeding mechanism andthe bank feeding parts of the loader is connected with the forwardpulleyshaft 10, so that it Wlll not interfere with and will beunaffected by the forward and backward movement of' the loader. Thismechanism as shown is substantially the same in construction and modeof. operation as the mechanism fully shown and described in applicationSerial No. 11,941, filed March 4, 1915. It comprises a ratchet wheel 26secured to the shaft 10,

and operated upon by a pawl 27 carried by a lever 28. The mechanism forreciprocatmg the pawl carrying lever comprises a driving lever 29 whichis reciprocated by a: crank 30 secured to the end of the cam shaft 3,and connected by a link 31 with the lever.

otion is transmittedfrom the driving lever to the pawl carrying leverthrough a driven to a'rock shaft 34, the arm 33 being connected'by anadjustable link 35 to the upper end =driven lever will therefore movewith the driving lever to the end of its stroke in this direction. Themeans for connecting the driven lever to move with the driving leverever comprising two arms 32 and 33 secured during the stroke of thedriving lever in the opposite direction consists of a sheet coir trolledlatch 37 carried by the driven lever, and arranged to engage a notch 38in the end of the driving lever. The latch is secured to the end of arock shaft 39 mounted winthe lower ends of the arms 32 and 33, and

1s moved in a direction to engagethe drivlng lever by a spring coiledaround the shaft. Movement of the latch in either direction isdetermined by stop lugs 40 formed on the arm 32, and arranged tostraddle an arm 41 secured to the rock shaft The arm 41 is connected toone end of a ratchet bar 42, the other end of which is arranged toslide'through a rocking bearing 43. The upper surface of the ratchet bargaged by a stop pawl 45 mounted on a. rock shaft 46- which is providedwith an arm 47. The end of the arm 47 is connectedby a link 48 with alever 49, which is in turn connected by a pin 50 with an'arm 51, whichforms a part of' one of the cut-out mechanisms.v

With this construction, the driven lever and connected pawl carryinglever willmove toward the left with the driving lever until the sheetoperates the cut-out. when the pawl 45 will arrest the movement" of thebar'42,

cific construction and arrangement of parts is provided wlth a series ofteeth 44 arranged to be enshown and described in embodying the in-' 1vention in the Cross paper feeder, it will be understood that thisconstruction andarrangement is not essential to the'broader features ofthe invention, and that the conaving explained the nature and object ofthe invention, and specifically described one form of mechanism in whichit may be embodied, what is claimed is r Y combination, sheet separatingmechanism, bank feeding mechanism, and a loader mounted for movementinto erative relationto the bank sheet separating .-mechanisms.
